If history remains true the Xbox 360 Spring update should be on its way soon, but unlike previous updates we've heard nothing about new features. According to a tip sent to Joystiq regarding the spring update there are nearly 80 new features and tweaks possibly incoming for the Xbox 360.
The completely unconfirmed list can be found after the jump but we can tell you it includes some features we've dreamed for. Voice chat conferences for up to four people, an Inside Xbox Portal which includes news, entertainment, weather and various community features, downloading audio from feeds (such as the Xbox 360 Fancast, or other podcasts we guess), a DRM check for downloaded content which lists items that will not be accessible when disconnected from Xbox Live and a new (hopefully working) way to correct the DRM issue are some of the features on the list.
Other notable features include being able to delete games from your played games list if they list a gamerscore of zero (and zero obtained achievements) and the ability to save game data onto the hard drive for faster loading (presumably the way PS3 handles the feature).
The most interesting addition is the ability to calibrate motion sensor based peripherals again pushing the Wii-like controller rumor into the limelight.
Keep in mind that this all squarely falls under the category of "rumor" for the moment. We'll let you know as soon as we hear otherwise. Find the full list of (rumored) features after the break.
